Ireland's PR-STV electoral system:

a need for reform?

 

The Irish electoral system: since independence in 1922 members (TDs) of the Irish parliament, Dáil Eireann, have been elected by the system of PR-STV (proportional representation by the single transferable vote). This system is enshrined in the 1937 constitution, which can be amended only by referendum. In both 1959 and 1968 a referendum took place on a proposal to replace PR-STV by the single-member plurality system ('first past the post'); on each occasion the proposal was defeated.

For an explanation of how PR-STV works, and a specimen ballot paper, click here. Since voters may rank order all of the candidates listed on the ballot paper, PR-STV offers voters a choice of candidate between parties, within parties, and without regard to party. Consequently, there is both inter-party and intra-party electoral competition.

From time to time the question is raised in Irish politics as to whether PR-STV is dysfunctional in its effects and should be replaced by something different, perhaps a mixed system along German lines. The electoral reform debate tends to be impressionistic rather than evidence-based and usually lacks a comparative perspective. In the two referendums of 1959 and 1968, the central issue was the alleged tendency of any kind of PR to produce unstable and internally divided coalition governments, and perhaps to lead to the collapse of democracy, compared with the supposedly 'strong, effective, single-party governments' produced by the single-member plurality system. This line of argument is no longer taken seriously and the merit of the principle of proportional representation is now generally accepted. The issue of contention is whether STV is the best method of realising this principle.

 

Among the points made AGAINST retaining PR-STV as the Irish electoral system are:

 

Among the points made FOR retaining PR-STV as the Irish electoral system are:

 

OVERALL: The impact of electoral systems on many aspects of politics in any given country is less strong than is sometimes assumed. While electoral systems do have an impact on, for example, the proportionality of electoral outcomes, and to a lesser degree on the shape of party systems, it is not realistic to expect a change in the electoral system to transform the style of politics in a country. For example, PR-STV was not responsible for the economic boom in Ireland and neither is it responsible for the economic crisis. Generally, political institutions that operate in one fashion in country A will not necessarily produce the same consequences if transplanted to country B. Comparative cross-national research suggests that the causal connection between the electoral system and the constituency role of MPs is much weaker than some people imagine, and it is very likely that the demand from voters for constituency service from their TDs, and TDs' readiness to respond to this, would be altered little by the adoption of a different electoral system in Ireland.

Chapters on a number of countries explore the relationship, if any, between electoral system and MPs' behaviour, and there is a chapter assessing the record of PR-STV in Ireland: 'Ireland: the discreet charm of PR-STV'

John Coakley and Michael Gallagher (eds), Politics in the Republic of Ireland, 5th edition (London: Routledge and PSAI Press, published August 2009). Chapter 4 by Richard Sinnott on 'The electoral system', and Chapter 8 on 'The constituency role of Dáil deputies', both discuss the issues
